Maurizio is a stubborn boy who grew up near Fiumara, where people threw away things they no longer needed. This outdoor garbage dump became his playground, where he began to dream of playing in a town band amidst wrecked cars and other treasures of all sizes. Mamma Rosa believes that his musical aspirations are a childish whim, a luxury that families cannot afford. Therefore, between the good advice of the donkey Mos è and the prank of the chicken N'Giulina, Maurizio faces a series of increasing adventures, realizing that if his dream is to come true, he must be determined to persevere to the end.
